The Aeros Profi is a Ukrainian high-performance ultralight trike wing, designed and produced by Aeros of Kyiv. The wing is widely used on Aeros trikes as well as by other ultralight aircraft manufacturers.[1]

Design and development

The base model Profi wing is a cable-braced, king post-equipped hang glider-style wing for two-place trikes, while the Profi TL is a "topless" design, lacking the king post and using streamlined lower lift struts instead of wires. The topless design lowers the overall height of the wing and allows storage in lower-roofed hangars. A carbon fibre leading edge insert is optional, while winglets are standard on the TL model.[1][2]

The wing is made from bolted-together aluminium tubing, with its double surface wing covered in Dacron sailcloth. Its 10 m (32.8 ft) span wing has an area of 14.5 m2 (156 sq ft), a nose angle of 128° and uses an "A" frame weight-shift control bar. An electro-mechanical trim is optional.[1][3][4]
